Patented Apr. 1, 19 50 1 UNITED- STATES PATEN T o ncE ALBERT E. GRANT, or Nnw Yo N. Y., ASSIGN'OB To GRANT HEAT MACHINE con- PORATION, or NEW YORK, N. Y., A CORPORATION or DELAWARE OIL FEEDING AND BURNING APPARATUS My invention relates to generating and burning hydrocarbon gas, the object of my invention is to provide an improved device forthis purpose that is simple in construc Referring to the drawings-which form a part of this specification I Fig. 1 is a longitudinal artly sectional view of a gas generator-and urner embodying my invention.

Fig. 2 is a cross sectional view of the supply reservoirs for the large and small burners respectively, and discloses the general arrangement of the apparatus .A A Arespectively indicate flanges into which are screwed rods B, B and B respectively. The upper ends of the rods BB extend thru bosses G C respectively, cast integral with a tank 0, adapted to hold oil,

said tank being provided with the cover C Suspended'from the bottom of the tank between the supporting rods BB is an electric motor D,an air pump and blower E, and two oil pumps F and F respectively, all of which are mounted on shafts in gommon alignment asindicated by D and shown in dotted lines in Figure 2. D indicates the casing of the air pump. Formed integral with and extending upward from the bottom of the tank, is"a r1ng G, into wliich is screwed a collar G in vertically adjustable relation thereto. The ring an'dcollar pro-. vide a chamber for oil indicated by H in which the oil level is maintained at a lower level than that maintained inthe chamber H I indicates a conduit for air, which is clamped between the flanged ends of the air ump casing and the burner casing J, by, bolts K, located at each side thereof. Thecasing J is provided with an annular chamber J which holds oil to supply the large burner, and with a smaller annular chamber L, inwhich is located a cylindrical wick M, of porous refractory material freely removable therefrom after the central spreader N is first removed. The spreader N rests in a central bore N formed in the tubular por-- tion 1? of the casing J and is formed with? vertically extending grooves in its sides thru which air may pass from the conduit I and Application filed February 11, 1928.

lower part of the casing J to the upper end of the wick M to supply air to the small cen tral burner comprising said wick. A. central air deflecting collar 0, shaped substantially as shown, is also supportedby central tubular portion P, of the casing J, to deflect air which passes fromthe lower side of the casing thru passages R, formed between web portions S, which connect the central tubular portion P with the inner wall of the chamber J The top of the burner comprises a ring T, formed in a separate casting to permit of easy moulding of the casing J, and provides an annular passage'T for the gaseous fuel formed by the mixture of air passing thru the chamber J when mixed with the hydrocarbon gas generated by heattained at. the proper levels in the respective 4 burners by controlling the level of the oil at an equal corresponding height in the chambers H and H respectively. This is accomplished by pumping oil from the main reservoir W thru ipes W and W by the gear pump F whic discharges into chamber H y flowing over the top of the ring G into chamber H in which the oil is maintained at a level equal to the height of thertop of the return pipe X, thru which all surplus oil not consumed by the burners is drawn by the pump F and returned to the reser voir W thru pipes X and W A plus valve Y controls the passage thru the pipe V and is operated by thermostaticallycontrolled means (not shown) to autoand burners supported therein, is

drawn thru one end of the motor casing to the to said burners, and means for maintaining blower and discharges therefrom thru the oil in each of said burners at constant preconduit I and casing J, a part passing thence determined levels.

thru the passages R to the underside of the ring 0, and being deflected downwardly over passage T above which the gas generated is burned. Also, air is passing thru the passages in the sides of the spreader N and uniting with the gas generated at the upper end 7 of the porous wick 'M. When too much heat is being generated, the main burner may be shutoff by closing the valve Y, either manualsignature. the oil in the chamber J and thence thru v 1y orautomatically, and the small burner allowed to continue to operate, and also serve to i to the main burner when the oil is again admitted to the chamber J A manually operated valve is'located in the pi e V to be closed at any time desired.

claim as new r v 1. A device of the-character described comprising a motor, an air pump and two oil pumps driven thereby, a large burner and a i :5 small buriier located adjacent thereto which serves to generate heat and also as a pilot light for the large burner, a chamber for oil in communication with the large burner and a chamber-for oil in comniunication with the to small burner; the level of the oil in said first chamber being maintained above that of the level in the second named chamber, one of said pumps acting to supply oil to both of said chambers and one acting to return the surplus oil from said chamhersto the source of supply.

'2. In combination, two independent burners each having a chamber for oil, one of which is of relatively small capacity and 46 serves as a pilot light for the other burner, a wick of porous refractory material in one of said chambers, and means for maintaining oil at a level slightly below the top of said wick,

and for mamtaining a predetermined 'oil I I level in the chamber of the other burner,'and' a r pump, and means'for conducting air from said air pump to said burners.

aving thus described my'invention, I I

A device of the character described com- 7'- pnsmg a supporting frame, a casing adapted ,7 ID to hold oil, a motor, an air pump and oil I .pumps suspended from said casing, an oil urner, a conduit for air leading from saidairump to said burner, conduits for oil leadm from said pumps to the casing, conduits or oil leading-from said casing to said burners, and means for maintaining oil in each of said burners at constant mined levels.

A device of the character described com: prising means for holding oil, two independ ent burners located adjacent to each other and predeteradapted to be operated simultaneously, a 5 motor, an air pump and an oil pump operated by said motor, conduits for an and 011 leadmg from sa1d a r and oil pumpsrespectively In testimony whereof I have aiiixed my ALBERT E. GljAN'l.
